Interesting update on battery drain on my series 8. I have a long run scheduled for tomorrow and was pretty much certain my battery wouldn’t last. A 30 minute run on Wednesday drained 34% battery with no headphones, volume off and watch heart rate monitor off. I also left my external heart rate monitor at home as they’re essentially not working with the beta update. Yesterdays 54 minute run drained around 60%
By comparison… today I went out again for a 30 minute run with internal hrm disabled, no headphones etc. Today though I also disabled cellular on my watch. Just back and I’ve used 11%. So having cellular active (but no streaming etc) drained around 23% battery for me on a 30 minute run.
I’ll leave everything off again for tomorrows run but will start adding stuff back in next week (apart from cellular)
